I can not see any way to fix my misaligned power steering pump.
The bracket that mounts to the water pump seems to be causing this and does not look to be bent.
Wrong bracket?

Maybe if the bracket isn't bent, maybe it needs to be bent in the direction to straighten that belt out.

That's an option however it is really heavy duty and going to take some serious force to tweak it.
-
Align your line of sight with the front or rear plane of the pulley face. Does the inside of the bracket need to move rearward, or does the outside of the bracket need to move forward, or___________? Is it missing the rear support that anchors the outside of the pump to the exhaust manifold stud (image)? I would avoid bending brackets unless there is no alternative, since it almost always introduces new alignment issues. Can you post additional pics of the bracket mounting to the block, etc?
-
It is the inboard bracket that attaches to the water pump causing the problem which has no adjustment.
The alignment is off with the outboard belt tension bracket disconnected.
Looking from top down the pump needs to be rotated clockwise.
My setup is exactly like the top one pictured in your image.
-
Looking at it from your picture, it appeared as the side of the pulley closest to the block needs to go towards the firewall, which would in turn bring the side of the pulley closest to the fender out towards the radiator. Which is the same as looking from the top down and rotating clockwise on a vertical axis.
-
Lets see a picture of the rear bracket.
-
When I remove the bolt on the tensioning bracket and loosen the long bolt through the water pump bracket this is how the pump wants to sit. No reasonable amount of prying between the bracket mounted to the exhaust manifold and head and the slot bracket on the pump will work.
I know it looks like add a spacer / stacked washers but that will not work plus notice in the first picture above how close the power steering and alternator belts are.

You may not have a matched pump to bracket, they are not all the same.
When I replaced my pump in my 74 K5 the replacement pump and reservoir did not fit the bracket properly.
After getting the correct pump all fit fine.
The differences are subtle but exist.
Just a thought.
-
I ran into this same issue... And I simply just used a lot of spacers aka washers to get it lined up properly.

I think that is it!
Unfortunately I returned the original pump for the core.
The pump wants to sit closer to the engine with a spacer between the manifold / head bracket and the slotted bracket on the pump.
I just tried adding a spacer between the fixed manifold / head bracket and the slotted bracket on the pump and it is close but now the belts touch.
Thank you.

I tried a stack of washers moments ago even though I could see it would cause the belts to touch.
I think I have the wrong pump as blazer74 suggested.
Thank you for your help!

I thought I had a picture of what mine looked like but it looks almost like the shaft is too long on that pump.

You are right. If the pulley was set back a little I could make it work.
I rented a tool to remove and replace the original pulley I know it is seated fully but maybe the shaft on this pump is too long.
You guys are GREAT!!!!!!
Thank you all!

Mine was a delco reman from Amazon and was wrong.
I went to napa and they had the correct pump and and reservoir.
-
Recheck harmonic dampener mounting depth and/or get a 2 groove WP pulley and use the outer groove....

Thanks I checked the other parts stores today no luck they were all the same as what I have.
I'll try Napa tomorrow.

I think the damper and crank pulley are okay. The alternator / water pump belt looks perfectly aligned.
Before I mess with anything else I am going to try Napa as blazer74 suggested.

Was this a running engine prior to this issue or are you putting this together?

Original running engine.
I started with replacing the worn, sloppy steering gear. While I was at it I replaced the pump and lines because the PS fluid was burnt, brown and stinky.
Although the original pump was working I did not want to risk pumping junk into the new steering gear.
Unfortunately I returned the original pump for the $15 core.

not being familiar with your set up nor powersteering brackets but with that bracket that appears to be bent from the factory. is it possible to flip that bracket around so its not bent outward but inward
-
How long ago did you return the core? Maybe you could get it back.
All started with the pump change, could also have a longer snout.

It doesn't look like that would work. The weld nut will be on the wrong side.
I'll give it a try tomorrow.

I changed the pump, lines, and steering gear February 2015.
My core is long gone.
Stupid me. I knew there was a problem when I installed the the new pump a year ago but at the time the truck was new to me and I had so many other issues to deal with I let it go until I repaired all of the other major problems.

maybe i wasnt clear or maybe im not thinking clear. but the bracket that bolts from the inboard side to the pump (from this angle it only looks like a piece of flat bar with two holes and a bend)
-
Wow! Makes me leery to want to replace my leaking pump and lines now! I don't want that headache! And knowing my luck, it's exactly what would happen to me! I swear every time I go to the parts store for something for this truck I get blank stares from the staff like I have lobsters crawling out my ears or something! Lol! I hope you can come up with a workable solution!
-
I usually look things up on my own prior to going to the auto parts store so I know in m getting the correct parts or I show them the info from their website when the can't find what I want.
I like dealing with the napa people in their smaller stores but watch the prices on some things that are napa re-boxed same part as the discount chain stores but more money.
A cardone steering gear can be as much as 20 bucks more at Napa vs others and the exact same part and box. I bought it at oriellys cheaper.
I've also bought a evap purge sensor for my ranger at Napa in a Napa branded box and was a motorcraft part so you have to watch.

Having read through this a few times, have you put a couple washers between the pump and the inboard non adjustable bracket, the one Irish_Alley pointed out
That should push the pump closer to the engine, rotating the pulley clockwise, as viewed from the top

The inner bracket is as pictured here...

Will the pulleys align if you loosen or remove the bolt circled in yellow in the image below?

Just do yourself a favor at this point http://www.ebay.com/itm/SBC-CHEVY-327-350-383-ALUMINUM-POWER-STEERING-BRACKET-P-44302-/331662998542?hash=item4d38a7bc0e:m:m9yuO57CybQQO7ReQvUd9bg&vxp=mtr

Bd I don't remember my bolt being that high in the bracket on my 86 is that normal

His truck is a '75 model. The '86 models used a different configuration.

Thanks everyone.
I had a long winded reply ready to post when it occurred to me that maybe I have the wrong water pump.
I'll be back later today if I have time to measure my water pump and run to the store to measure a new one.
If not I'll be back tomorrow.
Thanks again. I'll be back.

There are really only two types of water pumps for the SBC; long and short. Your water pump IS the correct pump but something else is not correct.
Also looking at previous pictures it seems like your reservoir for the steering pump is WAY to far over as it needs to be sitting more upright.
I know when I was putting my truck back together I was having stupid issues everywhere and the power steering pump wasn't fitting correct. It wasn't until I realized that the new timing tab I put onto the truck was interfering with the cradle bracket for the pump.
So instead of going and getting a new timing tab I just modified the cradle for the steering pump.

It is just a funky angle of the picture. You can see the valve cover is vertical. The filler neck is close to vertical if I had taken that picture looking straight down.

This is an interesting drawing.
The brackets are the same as mine but the pump has a threaded shaft with a keyway. The shaft on my pump is longer and press fit.
I looked at a pump like that at Napa today ('69 Camaro) it fits my brackets and it has a shorter shaft which I need. The problem with that one was they don't carry a pulley for it.
The last drawing VileZambonie posted is my pump with a pressed on pulley but different brackets.
I think we're on to something.
-
That's an actual Gm parts manual pic. I will say you have the wrong pump again.
Should have the keyed pump with a nut holding the pulley on from what I see.
Also explains the vertical angle being wrong that you mentioned.
75 C10?
-
Should be able to find a pully., takes a special shallow nut

I agree(d) with you. The pump is the most likely suspect.
Every brick and mortar and online store calls for the pump I have but the drawing you posted from the manual shows differently.
I have a '75 K10 w/o AC.
I'm guessing the pump I have maybe for an AC truck however none of the searches I have done including the manual offer any options for the pump.
I am going to hunt down a pulley and nut for the short shaft pump you pictured.
Is that the style pump you have?
-
Yes, look at a pump for a 74. Don't think the maters as far as A/C for the pump only the pulley is a double.
Gmpartswiki.com is a great site for part applications and numbers.
-
The hunt begins.
Thank you very much for your help.
